Infrastructure maintenance planning is a large-scale optimization problem of when and on which components to carry out so as keep the whole infrastructure in good condition with minimal cost. Recent advances monitoring techniques have enabled timely response each part regardless age. In addition condition, spatial structure also important for cost-efficiency since traveling costs and/or setup c...

As a maintenance strategy to reduce unexpected failures and enable safe operation, condition-based (CBM) has been widely used in recent years. The decision criteria of CBM the literature mostly originate from statistical failure data or degradation states, few which can directly effectively reflect current state analyze condition monitoring data, measures, reliability together at same time. In ...

Maintenance helps to extend equipment life by improving its condition and avoiding catastrophic failures. Appropriate model or mechanism is, thus, needed to quantify system availability vis-a-vis a given maintenance strategy, which will assist in decision-making for optimal utilization of maintenance resources. This paper deals with semi-Markov process (SMP) modeling for steady state availabili...
